MACHINE FOR TREATING HIDES,

SPECIFICATION forming part of Letters Patent No. 363,295, dated May 17, 1887.

Application filed October 25, 1886. Serial No. 217,119. (No model.)

To all whom it may concern.-

Be it known that we, WILHELM LICHTEN- BERG and Josnri-r BALOUN, both ofMilwaukee, in the county of Milwaukee, and in the State of NVisconsin, have invented certain new and useful Improvements in Machines for Treating Hides; and we do hereby declare that'the following is a full, clear, and exact description thereof.

Our invention relates to machines for treating hides preparatory to tanning; and it consists in certain peculiarities of construction and combination of parts, to be hereinafter described with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a side elevation of a machine constructed according to our invention; Fig. 2, a front elevation of the same; Fig. 3, a vertical transverse section on line at m, Fig. 2; and Fig. 4, a detail view of the knife-shaft.

Referring by letter to the drawings, A represents a suitable frame, having its sides provided with slots a and guides b for boxes 0,

that receive the journals d of a drum, B, and said sides of the frame are also provided with bearings e for adjusting-screws O and sockets f for the upper ends of spiral springs g. The journal-boxes a have their upper sides recessedto receive the lower ends of the spiral springs 57, and the bottom sides of said boxes are also recessed to receive the upper ends of similar springs, ii, that are seated in collars t on the adj usting-screws.

3 5 The periphery of the drum B may be of any suitable material, though we prefer to make the same of rubber webbing. Atransverse slot, 9', is made in the periphery of the drum, and to one head of the latter is pivotally connected 0 a bar, 1), that engages this slot, the free end 70 of the bar being extended beyond the head of the drum that comes nearest the operator. The free end is of the bar D is cut away to be engaged by a lookinglever, E, pivotally connected to the adjacent head of the drum, and this lever in turn engages a rack-plate, F, that is secured to said head. The transverse bar I), pivoted lever E, and rack-plate F form a clamp mechanism, whereby the hides to be treated are held upon the periphery of the drum. One of the journals (7, of the drum B has keyed thereto a gear-wheel, G, that meshes with a pinion, H, loose on a shaft, m, that projects from a stud, a, on the adjacent side of the frame A, said pinion being provided with a crank, I.

Journaled in the frame A above the drum B is a shaft, K, provided at its ends with pulleys L, that are intended to have belt-connections, M, with suitable driving-pulleys. The

shaft Kis preferably provided with two series 6 of overlapping right-angular recesses, o 0, that diverge in opposite directions, and are longitudinally arranged at an angle to the horizontal plane of said shaft. recesses 0 0 of the shaft K are knives N N, preferably adjustable, and each of these knives corresponds in length to its respective recess or seat, so that said knives in one series will overlap those in the other and have a cut in an opposite direction thereto, in order that no portion of a hide may escape being acted upon.

The frame A is provided with ears 0, that form guides for a pressureplate, P, by which the hides are stretched in their passage through the machine, and this pressure-plate has its ends connected to spiral springs p, the latter being in turn secured to the ears, thus permitting said plate to yield and accommodate itself to inequalities in the hides. The pressure plate 1? is located in the rear of the knife-shaft K, and just in front of this pressure-plate the frame A has secured thereto a hood or shield, Q, that deflects the cuttings.

The screws 0 are operated to vary the distance between the periphery of the drum B and the knives N N on the shaft K, the springs g h permitting said drum to yield in a vertical direction,whereby the stroke of said knives is cushioned and sufficient play given to accommodate any inequalities that may be in the hides.

The knives on the shaft K being removably secured thereto, one set may be substituted for another, according to the requirements of the work to be performed; or, if found more desirable, we may provide the machine with a series of knife-shafts, each having the knives thereon adapted to some special branch of said Removably secured in the scribed, with the flesh side out.

work, and for finc-hairing the hides it is intended to employ suitable stones in place of knives.

By our machine the hides can be fleshed, haired, and fine-haired, these operations being successively performed as follows: In the first operation one end of a hide is secured to the drum A by the clamp mechanism above do The operator turns the crank I to revolve the drum, and thereby carry the hide under the knife-shaft K at such speed as may be most desirable. Theshaft K is run at a very high rate of speed, and the knives thereon operate to remove the flesh on the hide during its passage under said shaft. After a hide has been thus acted upon, it is released from the drum and an unfleshed one clamped thereon to be acted upon in the samemanner. The fleshed hides, after being limed, are again run through the machine, the hair side being uppermost, and the knives on the shaft K being changed to suit therequirements of this operation of hairing. After the hides have been haired, they are bated and again run through the machine to be fine-haired, and inthis operation. stones of sui table kind are employed instead of k nives.

Our machine is very simple in its construction, effective in its operation, not liable to i get out of order, and always underthe control of the operator.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

In a machine for treating hides, the main frame A and drum B, provided with a mechanism for retaining a hide on its periphery, in combination with a continuously revolving shaft, K, arranged adjacent to the drum and provided with a series of angular recesses longitudinally arranged in a helical direction, knives or stones N, adj ustably secured in said recesses, and 1neans,substantially as described, for actuating the drum independent of the knife-shaft, as set forth.

In testimony that We claim the foregoing we have hereunto set our hands, at Milwaukee, in the county of Milwaukee and Statepf Wisconsin, in the presence of two witnesses.
